Substitute Part Grouping Explanation

Substitution eligibility for the MX7672KN03+ is determined by the following critical parameters:

Primary Substitution Criteria:

• Resolution: 12 bits
• Sampling Rate: 308 kSPS
• Number of Inputs: 2
• Input Type: Single Ended
• Data Interface: Parallel
• Architecture: SAR
• Reference Type: External
• Package: 24-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Operating Temperature Range: 0°C ~ 70°C
• Voltage Supply Compatibility: 5V nominal operation with -10.8V ~ 13.2V range

Substitute Parts Identified:

1. MX7672KN10+ (Parametric Equivalent): Identical electrical specifications and package configuration. Active product status provides ongoing availability and supply chain support.

2. ICL7126CPLZ (Direct Manufacturer Substitute): Listed in the original part's substitutes field. Note: This part functions as a display driver with 4.6-digit resolution rather than a 12-bit ADC. Substitution requires functional compatibility verification in the target application.

Parameter Comparison

Engineering Selection Recommendations

MX7672KN10+ (Recommended Primary Substitute): The MX7672KN10+ is the preferred substitute for the obsolete MX7672KN03+. Both parts share identical electrical specifications, package configuration, and operating parameters. The MX7672KN10+ maintains active product status, ensuring continued availability and supply chain support. Both components are ROHS3 compliant and carry equivalent environmental certifications. The primary difference is packaging format (Tube vs. Bulk) and product lifecycle status.

ICL7126CPLZ (Conditional Substitute): The ICL7126CPLZ is listed as a substitute in the original part documentation but represents a functional departure. This component is a display driver rather than a standalone ADC converter. Substitution is only appropriate for applications where display driver functionality is required. The 40-DIP package is physically larger than the 24-DIP footprint of the MX7672KN03+, requiring PCB layout modifications. The ICL7126CPLZ operates on a single 9V supply, differing from the dual-supply capability of the MX7672 series. This part is ROHS3 compliant and maintains active product status.

Frequently Asked Questions (FAQ)

Q: Can MX7672KN10+ directly replace MX7672KN03+ without design modifications?

A: Yes. The MX7672KN10+ is a parametric equivalent with identical electrical specifications, pin configuration, and package dimensions. No circuit modifications are required. The primary difference is product lifecycle status (Active vs. Obsolete) and packaging format (Tube vs. Bulk).

Q: What is the functional difference between MX7672KN03+ and ICL7126CPLZ?

A: The MX7672KN03+ is a 12-bit SAR ADC with parallel data output designed for general data acquisition. The ICL7126CPLZ is a display driver IC with 4.6-digit resolution designed for direct LCD/LED display interfacing. These components serve different functional roles and are not interchangeable in standard ADC applications.

Q: Does the ICL7126CPLZ require PCB layout changes?

A: Yes. The ICL7126CPLZ uses a 40-DIP package (0.600", 15.24mm) compared to the 24-DIP package (0.300", 7.62mm) of the MX7672KN03+. PCB footprint redesign is necessary. Additionally, the supply voltage differs (9V single supply vs. 5V dual supply), requiring power distribution circuit modifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The MX7672KN03+, MX7672KN10+, and ICL7126CPLZ are all ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity level).

Q: Which substitute should be selected for new production designs?

A: The MX7672KN10+ is the appropriate selection for new production designs. It maintains identical functionality to the obsolete MX7672KN03+ while offering active product status and assured long-term availability. The ICL7126CPLZ should only be selected if display driver functionality is specifically required by the application.

Q: What is the inventory status of substitute parts?

A: MX7672KN10+ has 803 units in stock (Tube packaging). ICL7126CPLZ has 1172 units in stock (Tube packaging). Availability should be confirmed with the component supplier for production volume requirements.
